Thank you for the bug report.

I wasn't able to duplicate this error message using the very latest
trunk build, or the latest version that is in the Fiji updater (and in
fact, I do recall fixing this very bug a while back).

Could you please run the Fiji updater ("Help > Update Fiji", making sure
to update "plugins/loci_tools.jar"), restart Fiji, and then see if the
file opens correctly?

Regards,
-Melissa
